AbstractFactitious Cheilitis is a rare skin disorder which has been seen in patients with emotional disturbances, particularly in cases with neurotic and personality disorders. However, there have been no reports of factitious cheilitis seen in cases of schizophrenia. This study reports on a case of schizophrenic disorder, where the patient was observed to develop factitious cheilitis whilst subject to unstable psychiatric conditions. The case reported here is of a 59 year-old female widow, who has experienced the delusion of being controlled, the delusion of being possessed. Been subject to auditory hallucination and vague somatic pain for eight years and had a very poor psychotropic drug compliance. Observation revealed frequent licking of the lips unrelated to drug-induced dyskinesia, but as a possibly linked response to hallucination whilst subject to an intense unstable emotional and painful state. Factitious cheilitis was proved with biopsy of the lips and pathological findings of acanthosis, hyperkeratosis and parakeratosis. After psychiatric and dermatologic care, her cheilitic condition improved. This study demonstrates that factitious cheilitis can be seen in a schizophrenic patient, specifically where hallucination and emotional instability coupled with long-term licking of the lips can result in factitious cheilitis. The relationship of skin disorder and psychiatric illness is discussed.
